Light L from the light source 53 is transmitted to a shadow member 21, and is irradiated on the surface of the substrate W held by the spin chuck 1. Consequently, the substrate W rotated is irradiated with the light from the light source 53 and a surface temperature is raised. The pure water rinsing liquid is thrown off by rotating the substrate W and the substrate can be dried. At the same time, the light L is irradiated to the rotating substrate W and the surface temperature of the substrate W is raised. Thus, the drying can be promoted.  <P>COPYRIGHT: (C)2004,JPO
